This looks fine, but I just realized this is the same thing as this[1].
Please coordinate these bindings.

I'll just leave this and comment on the other patch :-)

+Required properties:
+- compatible : Should be "ti,sn65hvs885"
+- reg : chip select number
+- gpio-controller : Marks the device node as a gpio controller.
+- #gpio-cells : Should be two. The first cell is the pin number and
+ the second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
+
+Example:
+sn65hvs885@3 {
+ compatible = "ti,sn65hvs885";
+ spi-max-frequency = <10000000>;
+ latch-gpio = <&gpio4 1 GPIO_ACTIVE_HIGH>;
+ reg = <0>;
+ gpio-controller;
+ #gpio-cells = <2>;
